Practice Questions

Concept Explanation

A standard deck has 52 cards: 4 suits (hearts, diamonds, clubs, spades) with 13 ranks each (Ace through King).

Key Counts

  • Red cards = 26; Black cards = 26
  • Face cards (J, Q, K) = 12; Aces = 4
  • P(one card drawn) = favourable / 52

Example

P(king) = 4/52 = 1/13; P(heart) = 13/52 = 1/4.

Common Trap

Confirm whether the deck is standard 52 cards with no jokers unless stated.
